On the other hand, I would recommend you to get the official programmer from SparkFun to save you some time messing with the serial to TTL converter. It is designed to fit nicely on the breadboard and MicroView.

I think it would be a bit more complicated for a 3.3V Pro Mini (I haven't tried it). You probably would need 5V to 3.3V level shifters on the TX, RX and RST lines. You would also connect the programmer's 5V pin to the Pro Mini's RAW pin instead of to VCC.
